Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Retombées économiques de la filière feuillus durs au Québec
No full textDepuis plusieurs années, la demande mondiale pour les produits forestiers évolue et demande une adaptation importante de l'offre des industries de ce secteur. Au Québec, ce secteur économique est divisé en deux grands groupes : la transformation des essences résineuses et celle des essences feuillues. Le premier secteur étant celui présentant le plus grand volume de bois transformé et le parc industriel le plus important, beaucoup d'efforts de recherche y ont déjà été consentis. Le secteur de la transformation des feuillus durs est moins bien étudié et il fait pourtant face présentement à plusieurs défis comme un manque d'approvisionnement en tiges de bonne qualité et des équipements de transformation souvent désuets. Pour savoir s'il est judicieux d'investir temps, efforts et capitaux dans l'amélioration des connaissances sur cette chaîne de création de valeur, il est avisé de connaître les retombées économiques de cette dernière. C'est dans cette optique que cette étude a été conduite
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Une analyse économétrique des transitions entre le décrochage et le raccrochage scolaires
No full textTitre de l'écran-titre (visionné le 20 juin 2023)La littérature portant sur l'éducation est en constante évolution et remonte à des décennies. Les nombreux angles d'approche des différentes questions en éducation font de cette littérature une connaissance riche et diversifiée. La littérature sur l'abandon scolaire ne fait pas exception. Elle touche à plusieurs aspects et mécanismes qui pourraient expliquer le phénomène de l'abandon scolaire. Cependant, la littérature qui traite du décrochage scolaire selon le parcours scolaire et le type de formation est inexistante. Pour traiter la question de l'abandon scolaire à l'aide du parcours des élèves et des différents types de formation, j'utiliserai principalement des modèles multinomiaux. Cette modélisation inspirée des chaînes de Markov permettra, avec l'aide des effets marginaux moyens, d'explorer et d'expliquer certains mécanismes derrière l'abandon et le raccrochage scolaire. En procédant à l'analyse, j'obtiens principalement que le système éducatif québécois couvrant la petite enfance jusqu'aux formations professionnelles semble réduire au maximum les risques d'inégalité entre les jeunes nés au troisième trimestre et les autres élèves dans leur probabilité de quitter le système éducatif avant l'obtention d'un premier diplôme. J'obtiens aussi que l'offre de formation professionnelle, ne nécessitant pas le diplôme d'études secondaires, semble offrir une voie de sortie aux élèves qui ont des difficultés à la formation générale des jeunes, plus particulièrement chez les garçons. Malgré l'offre de formation professionnelle qui attire une partie des garçons avec des difficultés d'apprentissage et qui leur offre une alternative au diplôme d'études secondaires, la diplomation chez les garçons reste un problème étant moins probable que celui des filles. De plus, la formation générale des adultes ne semble pas un bon outil pour aider les élèves à obtenir leur diplôme d'étude secondaire. En effet, la probabilité de diplômer de ce type de formation devrait être fortement supérieur à la probabilité de diplômer de la formation générale des jeunes. Cependant, ce n'est pas ce qui est observé.The literature on education is constantly evolving and goes back decades. The many angles from which different issues in education are approached make this literature a rich and diverse body of knowledge. The literature on school dropout is no exception. It touches on several aspects and mechanisms that could explain the dropout phenomenon. However, there is no literature that deals with school dropout according to the educational pathway and the type of training. In order to address the issue of school dropout by the educational pathway of students and the type of training, I will mainly use multinomial modeling. This modeling inspired by Markov chains will allow me, with the help of synthetic samples, to explore and explain some of the mechanisms behind dropping out of school. By proceeding with the analysis, I mainly obtain that the response of the education system seems to minimize the risks of inequality between young people born in the third quarter and other students. I also obtain that the offer of formation professionnelle, not requiring a high school diploma, seems to offer an exit route for students who have difficulties in formation générale des jeunes, especially among males. Despite the formation professionnelle offer that attracts a portion of boys with learning difficulties and offers them an alternative to the high school diploma, graduation among boys remains a problem that is less likely than for girls. In addition, formation générale des adultes does not seem to be a good tool to help students graduate from high school. Indeed, the probability of graduating from this type of training should be much higher than the probability of graduating from formation générale des jeunes. However, this is not what is observed
